Description
Technical field
The present invention relates to jaw crusher technical field, specifically the multi-functional jaw crusher in a kind of tooth plate three folding symmetric interchange type three chamber.
Background technology
Jaw crusher, is commonly called as jaw and breaks, and form crusher chamber by dynamic jaw and quiet jaw two pieces of jaws (also claiming tooth plate jaw), two jaw movements of simulated animal complete the disintegrating machine of material crushing operation.Its medium size being widely used in various ore and bulk materials in the industries such as mine, smelting, building materials, highway, railway, water conservancy and chemical industry is broken.
There are two large defects during prior art jaw is broken:
One is in the crusher chamber of " V " type after each circulation stroke work done, discharge be the material of a pile triangle volume.Because jaw crusher is typical single-particl crushing (not having lamination crushing), so the granular size set of dimensions moderate that triangle volume holds is poor, it is high that the on-the-sieve material (exceed the material of up to specification size) of discharging after screening returns heavily broken ratio, affects crushing efficiency;
Two is enter the solid accumulation of crusher chamber and shaky, thus affects crushing efficiency.We can analyze from three aspects:
1. because broken material is out-of-shape, not of uniform size mostly, between material and material, form very large cavity clearance, so make the material density passed through in the unit interval reduce, crushing efficiency is insufficient;
2. because the broken stroke (referring to the relative motion distance of two pieces of tooth plates) of every platform disintegrating machine is certain value, when have enter crusher chamber compared with the material flow of wide arc gap time, the last period of broken stroke will consume in this process of compact stockpile (after only having bank compacting, broken stroke just plays substantial broken work done), so, the loose effective broken work done reducing broken stroke of material flow;
3. be " V " type structure because jaw breaks crusher chamber, big upper and lower small mouth, has one material component is upwards existed during two tooth plates occlusion materials, so, when material loosening, be easy to that material is turned to, displacement or upwards takeoff, thus affect the effective broken work done of broken stroke.
More than analyze visible, the loose or dense degree of material flow affects the key factor that jaw breaks crushing efficiency.
Summary of the invention
The object of the invention is to overcome prior art jaw and break the defect that material flow is loose and material size concentration degree that is discharging is not high due to charging, provide the multi-functional jaw crusher in a kind of tooth plate three folding symmetric interchange type three chamber, thus improve broken work doing efficiency, improve jaw break equipment working condition, reduce energy consumption.
In order to reach above object, the present invention is achieved by the following technical solutions: the multi-functional jaw crusher in a kind of tooth plate three folding symmetric interchange type three chamber, comprises frame, transmission device, dual-crank-rocker mechanism and crushing pair.It is characterized in that, described dual-crank-rocker mechanism comprises front crank and rocker mechanism and rear crank endplay device; Dynamic jaw, front bracket and eccentric drive shaft before front crank and rocker mechanism comprises; Rear crank endplay device comprises rear dynamic jaw, rear bracket and eccentric drive shaft; Forward and backward dynamic jaw is articulated on eccentric drive shaft respectively, and eccentric drive shaft is connected with transmission device; Below on rear side of dynamic jaw before front bracket one end is articulated in, the other end is articulated in below on front side of rear dynamic jaw, and rear bracket one end is articulated in below on rear side of rear dynamic jaw, and the other end is articulated in frame;
Crushing pair comprises the swing tooth plate being arranged on fixed tooth plate in frame and before being arranged on dynamic jaw, and swing tooth plate and fixed tooth plate stand facing each other the sidepiece crusher chamber of formation three folding three-cavity structure, wherein descend cavity shape to be shape between parallel zone.
Core concept of the present invention: above prior art crusher chamber, design a compaction cavity to realize material flow density to improve crushing efficiency, thereunder design parallel chamber, an Asia again to realize even function in small, broken bits, and dexterously one end of composition compaction cavity tooth plate is designed to symmetric interchange type with one end of composition parallel chamber tooth plate.
The present invention has two large significant architectural features: one is set up parallel chamber in small, broken bits, an Asia in the lower end of prior art crushing chamber for jaw crusher, and a compaction cavity (in three-chamber) is set up in upper end; Two is the jaws forming above-mentioned three chambeies, its upper and lower angle and length all symmetrical, two is used interchangeably.
The present invention has three large significant functional characters:
Section 1 function: the function of sub-parallel cavity structure.
In the present invention, one section of parallel cavity shape structure is set up (because swing tooth plate moves along a curved path in the toggle of eccentric shaft, dynamic jaw, bracket composition in the lower end of existing crusher chamber, here parallel zone is dynamic, approximate, thus under be called sub-parallel zone).
The function of sub-parallel cavity shape structure is:
(1), make material evenly in small, broken bits.
From side cross-sectional, prior art crusher chamber is in " V " font substantially.It gives off the material that a pile is inverted triangle volume when broken power stroke finishes each time, see such as Fig. 3 (the discharge of materials district of abcd inverted triangle volume, EF is that stroke opens limit).In this triangle volume discharge areas, upper dimension is large, lower dimension is little.Again due to the characteristic that jaw crusher is single-particl crushing substantially, so the material emitted from this triangle volume discharge areas is exactly, bottom is thin, top thick, and uneven, the concentration degree of material size is poor.
Therefore, the present invention devises subparallel configuration chamber to replace, subparallel configuration chamber finishes at each broken power stroke, and what emit is the material of a sub-cuboid volume, see such as Fig. 4 (a ' the discharge of materials district of the sub-cuboid volume of b ' c ' d ', E ' F ' opens limit for stroke).Suppose that sub-cuboid volume is equal with del volume, obviously, the particle of the former material is much more even than the latter, and namely the concentration degree of material size is high.
Analyze extreme case again, under inverted triangle lumen type state, even floss hole is transferred to minimum, (i.e. the gap set to zero of crushing pair lower end, but exceed will tooth plate bump against and ruin machine), still can give off coarse fodder.
And under the parallel volume in Asia, floss hole size can be set according to required material finished size size completely and (will ensure that the volume of each discharge is all the material in this parallel zone, does not allow epicoele material omit in printing.The length in parallel chamber will be calculated during design.Under discharge volume the same terms, discharge material is thinner, and parallel cavity length is longer, otherwise can be short).
Obviously, bottom be provided with subparallel configuration lumen type thinner than the broken finished product material out of prior art " V " character form structure lumen type and evenly, this is one of superiority of sub-parallel cavity configuration.
(2), " granule, large output " is realized.
Subparallel configuration lumen type is that disintegrating machine realizes the high ratio of reduction (i.e. " granule, large output ") and provides the strongest necessary condition.Under prior art conditions, jaw is broken a congenital deficiency, and " asking broken fineness and ask broken output " is exactly conflict.When namely requiring that raw meal particle size is thin, need reduce floss hole, at this moment production capacity just greatly reduces; Otherwise, during as wanted productivity gain, then need to amplify floss hole, but at this moment discharging-material size is just large.The two can not be compatible.
Subparallel configuration lumen type can solve above-mentioned drawback, realizes the compatibility of " granule and large output ".According to the characteristic of above-mentioned subparallel configuration lumen type.As long as the material volume that we discharge after ensureing each broken power stroke is all be less than the volume in sub-parallel chamber, the method of " little pilled-in selvedge; discharge greatly " just can be utilized to solve (claim pilled-in selvedge size when the minimum stop of dynamic jaw bottom power stroke, during maximum stop, claim slack list size).Pilled-in selvedge size determines thing grain fineness, and slack list size determines mass rate of emission.Widen the distance (also namely strengthening stroke) of pilled-in selvedge and slack list, be conducive to discharging (but mass rate of emission will meet freely falling body rule, has a limit).
In a word, under prior art, the contradiction of " ask in small, broken bits with ask output " is under the condition of subparallel configuration lumen type, is resolved by the method for " little pilled-in selvedge, large stroke ".
Section 2 function: the function of compaction cavity structure.
By setting up a compaction cavity in crusher chamber upper end, it is made to eliminate space between material and material to greatest extent, improve material flow density, improve the work doing efficiency of broken stroke, under not changing jaw and breaking the prerequisite of any parameter (comprising broken stroke), improve crushing efficiency significantly.
1. utilize compaction cavity to tamp the material flow entered, improve the density of material flow.
Material flow after compaction cavity has been tamped, eliminate the gap between material to greatest extent, material density improves, and enters the material of crusher chamber fragmentation within the identical broken time, the corresponding raising of crushing.
2. material flow is in or enters crusher chamber close to " necessary gap " state, thus improves broken stroke work doing efficiency.
From broken stroke and " necessary gap ", relationship analysis " natural gap " and " necessary gap " these two concepts in " natural gap ".When different, the not of uniform size bank of a pile shape together time, can there is gap between material, this gap is called in " natural gap ".Nature gap is unstable, if there is external force to make material constantly change direction or do relative motion, nature gap constantly can diminish (namely bank is constantly tamped), when natural gap is little after certain value, no matter how motion material all can not continue to reduce gap again, material gap is at this moment called in " necessary gap "." necessary gap " is not an absolute probability, is theoretical relative concept.From " necessary gap " more away from material flow elasticity larger, the material flow elasticity more close to " necessary gap " is less.
Broken stroke dactylognthite breaks the move distance of two tooth plates from pilled-in selvedge to slack list.The broken stroke that each jaw is broken is a definite value.In broken two stages of spm: one is because natural gap has elasticity, the broken stroke incipient stage first overcomes the elasticity of material flow, and at this moment broken stroke does not produce substantial fragmentation; Two is etc. after completely eliminating material elasticity, and broken stroke just produces fragmentation to material.The material flow be under " necessary gap " does not have (or rarely) elasticity (identification can be analyzed so in theory).
So whether material flow entered this pass of compacting, was diverse for the broken work doing efficiency under same broken stroke.Material is through compacting, and material is in or enters crusher chamber close to " necessary gap " state, thus improves broken stroke work doing efficiency.
3. the displacement utilizing gravity to stop material in shattering process and spring.
Because jaw breaks crusher chamber be " V " character form structure, big upper and lower small mouth, is an angle during two tooth plates occlusion materials, makes material have the component upwards pushed away.Although this angle has been arranged on the limiting angle α (26 °) that maximal friction allows when designing jaw and breaking within, when material flow is loose, be easy to make material turn to, displacement or upwards takeoff, affect the effective broken work done of broken stroke.After a compaction cavity has been set up in crusher chamber upper end, press against a thick layer of material above the material in crusher chamber, the weight of this layer of material itself pushes down the material in crusher chamber, plays to stop that material turns to, displacement and upwards jump role.
4. make feed more steady.
Under prior art conditions, because all factors affect, the material entering disintegrating machine always has some to fluctuate, time few time many.Namely this material fluctuation affects output, reduces service life of equipment again.In invention, set up compaction cavity, be equivalent to be provided with a savings material bin, saved by it when charging is excessive, mended by it time too small and supply.Steady feed effect is played in certain degree, can constant rate of production, be conducive to again extension device service life.
Section 3 function: the function that tooth plate is designed to " three folding symmetries are exchanged ".
Swing tooth plate is designed to two ends and turns back to side an angle extend a section simultaneously by the present invention, and angle of turning back equals the angle [alpha] (α is for being less than or equal to 26 degree) of former crushing pair, and every edge lengths is 1/4 ~ 1/6 of former crushing pair.Also can fixed tooth plate and swing tooth plate three foldings (but knuckle is at this moment 1/2 α of such scheme) simultaneously, lower end is a parallel chamber equally, and effect is identical.
It is parallel chamber that three folded tooth plates like this form lower end after being combined into crushing pair, and changing is still parallel chamber below.
Because parallel chamber, Asia is chamber in small, broken bits, its work done will surmount coarse crushing chamber, so be high abrasion district, and the not substantive generation of compaction cavity is broken, wear away atomic, allow this heavy light abrasion position symmetry exchange, be conducive to the utilization rate extending jaw, reduce disintegrating machine and totally wear away cost.
Improvement crusher chamber designs, and arranges compaction cavity peace an actor's rendering of an operatic tune, promotes crusher chamber function, and to improve crushing efficiency, and dexterously one end of composition compaction cavity and the one end forming parallel chamber to be arranged to that symmetrical expression exchanges be core technology of the present invention.

Every section, the extension that swing tooth plate two ends extend laterally accounts for 1/6 ~ 1/4 of self tooth plate length whole, and described extension and tooth plate are structure as a whole or Split type structure.
In the crushing pair of face-off formation three cavity shape structure, three folded structures extended to form in isosceles trapezoid shape are opened at swing tooth plate two ends respectively to outside, knuckle is that the angle [alpha] (scope of α: 17 degree < α < 26 degree) of crusher chamber is to ensure that cavity of resorption is parallel, the lower folding end tooth plate face of swing tooth plate is parallel to the tooth plate face of offside fixed tooth plate, and lower end is a parallel chamber.
